The boiling of the solvent is accomplished by a peripheral heating jacket filled with diathermic oil, heated by an electrical element. The vapours are then convoyed to a condenser cooled by air or water. The condensed solvent is collected in a tank, for its reuse. The contaminants remain as a residue inside a disposable bag named “Rec-Bag” ; in case of liquid residue, by tilting the unit itself. The distilled solvent characteristics are not altered by the distillation process, which can be carried on repeatedly.

The units can be connected to a vacuum unit, suitable for high boiling solvents or for those flammable ones which have a close boiling point and flash point. The vacuum module can be equipped with an air operated vacuum pump or an electrical vacuum according to the need.
